The Right Way to Brush and Floss (Most People Get This Wrong)

Almost everyone brushes their teeth. Very few people were ever actually taught how to do it well — and small technique mistakes, repeated twice a day for years, add up.

Hold your brush at a 45-degree angle toward the gumline, not flat against the tooth surface — this is where plaque builds up most and where gum disease typically starts. Use short, gentle strokes rather than long horizontal scrubbing, which can wear grooves into enamel and push gums back over time. Don’t forget the inner surfaces of your teeth (the side facing your tongue) and your back molars — both are the most commonly missed areas.

For flossing, the motion matters more than most people realize. Curve the floss into a C-shape against each tooth and slide it gently below the gumline, rather than just snapping it straight down between teeth. If your gums bleed the first few times you start flossing regularly, that’s usually a sign of mild inflammation from plaque buildup, not that you’re flossing wrong — it typically settles within a week or two of consistent flossing.

Good technique, done consistently, prevents far more problems than any whitening treatment or expensive toothpaste ever will.
